I don't know of black sig in SC, yet. Tomatoes get fusarium, but only in late summer. I will get some Copper sulfate and try that anyway.

Not to sound like a broken record, but. . .
When bananas are lacking vital minerals and minor elements they become much more susceptible to Sigatoka. I would imagine leaf injury in general, including wind, over fertilization, or prolonged root saturation would all increase susceptibility to the disease. I suppose that is why copper is ultilized before signs of Sigatoka? Either way, I will use fungicide on any future planting material in an attempt to get a head start on the disease, especially now that I know Sigatoka seems to be lurking in our midst.
I haven't heard of any Black Spot that far north either. My theory is that I possibly infected my bananas after handling fruit from the grocery store. I say this because the wild bananas in my area do not have any bacterial spots.
